What´s that over there?

Uh, a ... fish? You could do better than that. What would you think about a logbook entry reading "aalrutte" in 18m, swarm of "sonnenbarsche" near the entrance and a big "hecht" under the platform? In the course we will learn to classify fish by colour, form and fins and learn a lot of interesting facts about lakes in Austria. Equipped with a waterproof fishwatcher slate the hunt can begin. Who identifies the most different species?
